ONE Adjust - Wireless Tattoo Machine - Stealth
The FK Irons One Adjust provides complete creative control, combining FK Irons’ signature power with an advanced stroke adjustment system. With a range of 2.0 to 5.0 mm in 0.5 mm increments, it adapts efficiently to lining, shading, and packing without requiring a power reset.
This pen-style machine features FK Irons’ patent-pending stroke adjustment technology, allowing quick stroke length adjustments in seconds. Developed with direct artist input, it delivers consistent performance and adaptability across a variety of tattooing styles.
Precision-balanced and fully wireless, the FK One Adjust includes a digital display showing voltage or hertz, providing real-time feedback on output. The display is fully ambidextrous and adjustable for both left- and right-handed artists.
Constructed from 6061 T6 aluminium, the FK One Adjust offers durability and comfort in a compact, ergonomic form. Its stealth finish, modular grip compatibility, and balanced weight distribution help reduce hand fatigue and support stable work during extended sessions. The anti roll cap keeps the machine secure on the workstation, and the machine is compatible with Ergo Shield disposable grips for additional comfort and hygiene.
